FLYING-MACHINE.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed September 4, 1919. Serial No. 321,670.

at Milan, Via Durini N. 24, Italy, has invented certain new and usefulImprovements in Flying-Machines, of which the following is aspecification.

The object of the invention is to provide a flying machine with meansapt to facilitate equilibrium in water and to render rapid and easystarting the flight from water.

With this and other objects in view, the improved flying machineconsists of a combination of parts as will be fully described withreference to the annexed drawing in which:

Figure 1 is a side elevational view of an improved flying machine of thebiplane type, the lateral wings being removed to clearly indicate theconstruction of parts.

Fig. 2 is a front view thereof.

Fig. 3 is a bottom plan view of the same.

Throughout the drawing -1 is the front cell structure consisting ofplanes 2-8, 4-- is the car, 5-67 are the engines with helices 8 's atail Plane, 9 is the horizontal rudder, pivotally arranged on axle -10,11- are the vertical rudders pivotally arranged on vertical axles -12.

. The floating system of the machine comprises a middle float -13 andtwo side floats -14.15.

According, to the present invention, said floats are provided withlateral wing-s or supporting surfaces 16-l718-19- arranged between themiddle float and the side floats and between the side floats anddepending parts of the machine frame.

In the construction represented in the drawing said second set ofsupporting surfaces are arranged between the side floats and theprojecting sections 20- of the uprights 21, said uprights forming partof the front-cell structure.

The supporting surfaces are preferably constructed of resistant andlight material; they are supported between the floats and uprights bymeans of stirrups 22 being secured thereto by bolts 23 and thesupporting surfaces or main portions of the lateral wings are arrangedstationary with respect to the floats and preferably inclined in orderto give rise to a vertical'water pressure, when the aeroplane progressesin water, said pressure being directed upward.

Having now particularly described the nature of my invention and in whatmanner the same should be performed, I claim:

In an aeroplane of the biplane type, a front cell having prolongeduprights, three floats mounted underneath the lower plane, the middlefloat extending longitudinally beneath the aeroplane, the side floatsbeing smaller in size and arranged at a level above that of the middlefloat, inclined wings arranged between the middlefloat and the sidefl0ats,.and inclined wings arranged between the ,outer side of the saidside floats and one end of the prolonged uprights of the cell.

In testimony whereof I afiix my signature in the presence of twowitnesses.
